The invention relates to hydraulic construction, namely, the protection devices and structures arranged in the composition of the intake structures, and is designed to protect juvenile fish from entering the intake.

Known way to protect juvenile fish from getting into the intake, including the formation of a reservoir of artificial currents [1].

The disadvantage of this method is the inability to provide records of places of concentration of juvenile fish to determine the location of the water intake.

The closest technological scheme and is basically a way to protect juvenile fish from getting into the intake, consisting of the formation in the water currents, and currents form a group of submerged hydraulic jets in whirlpool zones, located between the seats of maximum concentrations of juvenile fish and water intake [2].

Known water site, including adjacent perpendicular in plan to transit the channel end section of the inlet channel, which is provided with a vertical longitudinal wall dividing it into two branches with equal input sections, and the lower part of the sleeve is done expanding in plan in the direction of transit of the channel [3].

The disadvantage of this construction is weak capacity to carry out the functions of intake.

is the most closest to the technical essence and the achieved result is the intake device, including the recipient which is connected with the flow and located on the edge of the coastal edge, suction tubes connected to the pump, policebrutality and means for forming a hydraulic jet stream [2].

The disadvantage of this device is the low efficiency of fish protection.

The aim of the invention is the creation of effective hydraulic conditions in the zone of influence of the intake of necessary and sufficient for effective protection of juvenile fish from entering the intake.

Preliminary submission of additional consumption of water, flowing through the channel, the input of which is oriented at an angle of 90 degrees to the longitudinal axis of the watercourse, allows you to generate the hydraulic jet, actively interacting with the transit flow of the watercourse. At the same time as the capacity of the new course and its focus allow you to create the maximum resistance of the transit flow of the watercourse. As a result, at the confluence of two streams, favorable hydraulic-biological conditions that allow for effective water on the needs of consumers, there is effective protection of juvenile fish. Indeed, fed in the transverse direction of the hydraulic jet, to communicate the flow of the river, creates a powerful hydraulic screen shut-off and diverter fish fry, located in the flow stream. Secondly, the created hydraulic structure - formation along the coastal edge sustainable whirlpool area allows you to create a local section of the watercourse, in which virtually no juvenile fish. Thus, there is a possibility to take part of the expenditure from the whirlpool area needs water intake without causing damage to the ecology of the pond.

Placing the output of the channel upstream of water intake helps to form a stable hydraulic conditions allowing for efficient water of the whirlpool created zone formed downstream and distributed along the coastal edge. Placement of policebrutality below the receiving water body in the cross section of flow, characterized by the presence of final coordinates internal borders hydraulic jet (so-called point of collapse, characterized by a maximum elevation of water level and the presence of two mutually exclusive directions of flow velocity), effectively conveying the debris and juvenile fish downstream watercourse, which in many conducive to orientation policebrutality downstream.

According to claim 7 claims. The presence in the output section of the channel of a device for regulating the speed generated by the hydraulic jet. This operation allows p and the change in hydraulic conditions in the watercourse to maintain stable water conditions.

On item 8 of the claims. Use as a device for regulating the speed of the vertical panels mounted for rotation on a vertical axis and connected to the actuator, allows control of the speed regime of the hydraulic jet generated in the output part of the channel.

According to claim 9 claims. Supply the lower edges of the boards guide allows you to provide a more reliable moving shields.

In paragraph 10 of the claims. Implementation guides are curved in plan fully satisfies the conditions of the reliable operation of the boards.

In paragraph 11 of the claims. The presence of lateral niches, made in the coastal part of the channel is also responsible reliable operation of the boards and in General just means to control the hydraulic regime of the jet.

On p.12 of the claims. Placement of policebrutality in cross-section, in which is fixed the lower coordinate internal borders hydraulic jet, allows to prevent the entry of debris, and most importantly fish fry in the whirlpool area. When policebrutality creates a directional musorofiti stream.

On item 13 of the claims. Installation guide wall parallel to the coastal edge and opposite policebrutality, generate musorofiti, especiauy guaranteed removal of garbage and juvenile fish downstream.

On 14 claims. Run the output of the channel truepromise system in the form of blinds allow you to control the planned location of the hydraulic jet, while, in the context of changing environmental factors, the formation of stable water conditions on the needs of consumers. The presence of actuator fully meets the requirements of the control stream, providing rotation relative to the longitudinal axis of the channel.
